Increasing demands for flexible and fast manufacturing of prototypes in metal sheets have lead to the development of a new process; the ”SPIF” (Single Point Incremental Forming).

The process is used to manufacture complicated geometries in a single set-up, which usually requires multiple drawings, assemblies, bendings etc.

A sheet is clamped inside the rim and is drawn using a rotating pin tool, which is path controlled on a CNC machine (milling machine, turning lathe can be used, or a dedicated SPIF machine).

IPU-Manufacturing has the necessary knowledge and are able to assist in testing, instruction and manufacturing of components.

Benefits from using this process are:

• Low initial costs, no forming tools
• A short lead time
• CAD Drawing ->CAM ->CNC -> Finished product
• Flexible, forming without tools
• The possibility for larger deformations than with conventional deep drawing
• Complex geometries
